Failing to run sslstrip on kali linux 2021.3 getting "ImportError: No module named twisted.web" as an error

sslstrip depends on Python 2 and python-twisted-core. I don't know Kali, but I'd suspect that version 2021.3 doesn't support Python 2 anymore (or, at least, doesn't support it in full).

Kali is based on Debian, and according to Debian Wiki:

Quote:

Debian Bullseye includes a version of Python 2.7 (and a short list of related packages like setuptools still built Python 2 packages). However, these are only included for building a few applications which still require Python 2 as part of their build process. Python 2 is not supported for running applications and there won't be any security updates for Python 2 in Bullseye.

Debian only builds python3-twisted for Bullseye. The Python 2 module was dropped.

BTW, Repology doesn't list sslstrip as provided by Kali repos. Where did you get it from?

Python is just an interpreter, you can install any version of Python you want. Then just setup python symlink properly to newer version (via update-alternatives, for example).
Currently my Debian bullseye distro has two versions (2.7 - predefined, 3.9.2 - installed manually, or predefined too - don't remember

).

But it makes sense what python version sslstip requires.

This is pure python error. It means, you haven't installed specified dependency (twisted.web) yet.
Guess, you should install required python version. And reinstall sslsti then. That's all.

Yeah, 2.7 and 3.9.2 are both predefined versions.
Not sure about Kali, i.e. different distros - different distribution policy.

When I said "doesn't support" I meant "doesn't support in its official repositories". Of course, you can install anything with pip.

that is interesting. Would be nice to know how did you get it and how did you try to run it.
Actually it (sslstrip) is more than 10 years old. On its home page you can find how can you install twisted.web, it is documented.

Yeah, it says

Quote:

Install twisted: sudo apt-get install python-twisted-web

which won't work in Debian Bullseye because python-twisted-web isn't provided there anymore.

OMG. Did not dive this way, just was thinking from error text. Well, suspect the only way to make it work is to find and install it manually.
